Vertical loads are transferred through an assembly of units through the development shear between the units. When the units are placed next to each other in a tight arrangement, friction between the units is developed thereby mobilizing a large portion of the paved plane for load resistance. In order to develop the friction which develops the shear, the units must be continuous and contiguous within an arrangement.

The interlocking nature of the concrete pavers by default results in a continuous and contiguous assembly, however, it is good practice to follow these two basic rules when designing a segmental paved surface.

CONTINUITY OF FACESAt a minimum. the two opposite faces of a surface of concrete pavers must be contiguous. This will result in load transferring in basically one direction and is acceptable for linear arrangements under light loadingconditions. For higher load carrying capacity, continuity in more than one direction is necessary. This arrangement will transfer loads to all the of the neighboring units much like a space frame building system.

DISCONTINUITY OF LINES OF ACTION

Complexity in Pattern Design : Mobilization of large areas of the paved surface under load is directly related to the ability of the individual unit under load to transfer the shear to as many neighboring units as possible. Discontinuity of lines of structural action can be continually transferred from a unit in one direction to a unit in another direction through complexity in the laying pattern, such as 90 or 45 degree herringbone.

Complexity in Unit Design : Increased shear and discontinuity of action lines can also be achieved through a complex interlocking shape, such as the dentated unit. The complex shaped units offer several paths for loads to travel thereby involving a large paved area for resisting loads.

Paving is one of the most important and delicate part in a building as they are the reason for the good or bad look and it bears the surface wear and tear. Thank you so much for the share and I will visit your site again for more. Very good work and I will visit again for more. Keep it up.
